A Blue Wave Keeps Building

Nate Silver: “The streak of excellent polls for Democrats continues. The latest New York Times/Siena poll shows the generic ballot at D +8, and this week’s YouGov/Economist wave has it at D +12 among likely voters.”

“As a result, Democrats’ chances of retaking the Senate are up to 65 percent in our Deluxe forecast. That’s the highest they’ve been this cycle.”
